Summary

Fentanyl is a potent opioid, it is theoretically 100 times more potent that morphine and in severe acute postoperative pain acts faster than its congener (morphine ) for pain relief . In the literature there is no study that corroborates this theoretical assumption and proposes to compare which has fewer adverse effects. This drug produces effects similar to those reported for morphine but less magnitude and has the advantage that during the postoperative period respiratory depression, antitussive effect , gastrointestinal discomfort and physical dependence are manifested in a significantly less degree.

Trying to solve the management of postoperative pain relief , our objective is to determine by controlled clinical trial of superiority if in adult patients undergoing surgery , fentanyl reduces faster qualification time of severe pain to mild pain in the postanesthesia care unit compared to morphine.

Conditions

  • Postoperative Pain

Interventions

DRUG

Fentanyl

The nurse will administer 1 ug per kg during 5 seconds when the patient complain of pain (visual analog scale, VAS, ≥7). Immediately with the onset of drug administration a timer started; every 5 minutes the researcher assess the EVA and the drug will be administered if VAS \> 3, until the patient manifests as a lower pain VAS ≤ 3 (mild). The nurse in charge in the PACU will manage the drug and will take 100 ug of fentanyl which is diluted in 10 mL of normal saline leaving a 10μg per ml concentration, are not labeled and for the physical and chemical characteristics of both drugs (colorless) risks of unblinded is minimized.

DRUG

Morphine

The nurse will administer 0,1 mg per kg during 5 seconds when the patient complain of pain (visual analog scale, VAS, ≥7). Immediately with the onset of drug administration a timer started; every 5 minutes the researcher assess the EVA and the drug will be administered if VAS \> 3, until the patient manifests as a lower pain VAS ≤ 3 (mild). The nurse in charge in the PACU will manage the drug and will take 10 mg of morphine which is diluted in 10 mL of normal saline leaving a 1 mg per ml concentration, are not labeled and for the physical and chemical characteristics of both drugs (colorless) risks of unblinded is minimized.
